Patented Oct. 1, 1929 PATENT OFFICE NORMAN I. HARSHBERGER, OF CHICAGO, ILLINOIS SHIIN'GIIE Application filed September 21, 1925. Serial No. 57,562.

This invention relates to shingles and particularly to shingles made of flexible material. One object of the invention is to provide shingles which, when assembled on the roof,

will produce a very pleasing appearance and will at the sametime effectively protect the roof from the. weather. Another object of the invention is to provide shingles of such shape that they may be cut from strips or sheets without any waste. Another object is to so shape the shingles as to lock down the exposed portions. Another object isto shape the shingles so as to facilitate the proper and expeditious laying of the shingles.

Of-the accompanying drawings Fig. 1 is a plan view of a series of shingles showing how they are out from independent strips or sheets; Fig. 2 is a plan view of the shingles as they appear when assembled on the roof; Fig; 3 is a plan view ofan individual shingle; Fig. 4 is a plan view of an individualshingle of a somewhat modified type; Figs. 5, 6, and 7 show a modified type of shingle, these figures corresponding to Figs. 1, 2'and 3; Figs. 8, 9 and 10 are corresponding figures showing another modification; and Figs. 11 and 12 are modified forms very similar to the shingles of Fig. 10; Figs. 13, 14 and 15 show another modified form, and Fig. 16 shows another form.

Referring to any of these shingles it will be seen that the shingles may be out without waste from strips-or sheets 21 and the sheet may be of any width providing it is the width of the length of a single shingle or some multiple of that length. This is so because the edge 22 of each of the shingles corresponds in shape with the opposite edge 23 and the.

entire projection 24: corresponds in shape to the recess 25 on the other side of the shingle. This being so, the shapes shown, and other similar shapes, may be cut from sheets of the width indicated without any waste material except the ends of the sheets, and even these ends may be used for filling in certain portions of the roof where entire shingles are not-needed.

This manner of forming the shingles makes it possible to provide edges 22 and 23 of any particular curve that may be desired. A

size and shape of the combined shank and double curve such as is indicated in Fig. 3 may be produced, or straight edges as indicated in.- Figs. 1, 10, 11 and 12 may be provided for, or concave or convex curves such as are indicated by vFigs. 7, 15 and 16. Inthis manner the appearance of the roof may be modified to a very'great-extent and many beautiful figures may beprovided for such as are indicated by the various figures showing the shingles assembled on the roof.

The lugs 26 which project from the lower portions of the shingles may be used for the purpose of locking down the exposed portions by slipping these lugsunder the adjacent underlying shingles. As is indicated in case of the figures showingthe assembled shingles, these lugs pass through slits 27 formed in adjace'nt underlying shingles and in this manner the entire exposed portion 28 of each shingle is locked down at both of its ends thus preventing the tendency of these exposed portions to be blown upwardly or warping upwardly and causing an undesirable effect on the roof.

The lugs 30 which are formed in each case on the upper edges of the shingles are used in placing the shingles as they are laid, these lugs, and particularly the long edges 81, forming guides for laying the shingles by abutting the two adjacent edges and causing them to register. Furthermore, these lugs offer some protection to the root-particularly as they fall at the lapping portion of theshingles and thus increase materially the lapping surface where leakage is most likely to occur. 85

I claim as my invention: I

1. A shingle comprising a body portion, a shank projecting from the lower edge of said body portion and having a lug extending outwardly from each of the outer corners thereof, a slit extending inwardly from the lower edge of the body portion on each side of the shank, the said body-portion having a recess in its upper edge of the same size and shape as the lugs, whereby, when a plurality of said.

shingles are assembled on a roof in rows parallel to the eaves with the lugs of the shingles of one row interlocking with the slits of the shingles of an underlying row,

there will be a substantially constant overlap for all portions of the shingles.

2. A shingle comprising a body portion, a relatively narrow shank projecting from the 5 lower edge of said body portion and having a lug extending outwardly from each of the outer corners thereof, the said body portion having a recess in its upper edge of the same size and shape as the size and shape of the combined shank and lugs, whereby when a plurality of said shingles are assembled on a roof in rows parallel to the eaves with the lugs of the shingles ofone row underlying the shingles of an underlying row, there will be a substantially constant overlap for all portions of the shingles.

3. A shingle having a shank projecting from the lower side thereof, the shank having a lug extending outwardly from each of the outer corners thereof, the said shingle having a recess on the opposite side thereof, the recess being of the same size and shape as the size and shape of the combined shank andlugs, said shingle having a slit extending inwardly from the said lower edge thereof on each side of the shank, each of said slits being adapted to interlock with one of the lugs of an adjacent shingle when the shingles are assembled on a roof. a

h Ini testimony whereof, I hereunto set my NORMAN P. HARSHBERGEB.
